Engadget complained that the glass back easily cracked and that the camera was average. And we know from Anandtech benchmarks that the CPU/GPU is about half that of the iPhone 5.
Nice cherry-picking on the benchmarks. So the second fastest phone in the world is "slow". Gotcha.
Did they actually crack one or were they inferior based on the iPhone and ignoring all of the work they did to make it more damage resistant?
